Metal Core PCB material including Aluminum PCB,Copper Base PCB, Iron base PCB. Aluminum is popular in the market special in LED lights market because of Cost .
Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.
The 1st One .Aluminum PCB
Aluminum PCB , also,it is called Aluminium PCB,metal core PCB,mcpcb, IMS(Insulated metal substracte).
Aluminum PCB have 3 parts:
1.Circuit Layer (Copper Layer)
This is printed circuit copper foil layer, From 1.0 oz up to 8 oz (35um-280um). Min.Trace/space 5/5mil(0.127/0.127mm)
2.Dielectric Layer(Insulated Layer)
There are very good price and delivery time if the raw material made in China and Taiwan, we also,have many customer who choose Bergquist Thermal-Clad and Larid Tlam material,strict meet customer’s Requirement to manufacture the ALPCB.
3.Substrate Layer(Metal layer)
There are 4 types Aluminum, 1001, 3001, 5052, 6063. If no requirement of this from,we used 5052 for High thermal conductivity ( 2.0 W/m.k or more) , AL1001,AL3001 for 1.0 w/m.k to 1.5 W/m.k
Aluminum Clad PCBs
Lower operating temperature.
Reduce printed circuit board size.
Increase power density.
Extend the life of dies.
Reduce the number of interconnects.
Improve product thermal and mechanical performance.
Combine power and control.
Improve product durability.
Enable better use of surface mount technology.
Expedite heat sinks and other mounting hardware.
Replace fragile ceramic substrates with greater mechanical durability
Price is based on the requirement of LED PCB
1. PCB thickness: 0.6 – 3.0mm, always thickness more ,price higher
2. Thermal conductivity: 1.0 – 10 W/m.k , thermal conductivity higher, price higher
3. Material factory: Bergquist, Laird ETC, made in US factory that is more expensive than China.
The 2nd one: Copper Core PCB
Copper core PCB is a copper substrate + Insulated layer + copper
Copper core PCB is a copper substrate + Insulated layer + copper circuits layer PCB,also, it is called copper substrate pcb, copper based pcb,copper clad pcb.
As a MCPCB manufacturer,we made various Copper core PCB for customers,
Which used for High Power LED lighter ( 1000W+ ) and power supply.
In LED field,there are 4 types of Copper based Circuit Board.
2. COB Copper PCB( Chip on Board copper PCB)
LED chip Direct thermal sink to copper substrate.
3. Direct thermal path,no dielectric layer under the thermal path pad.
4.Direct thermal path,no dielectric layer,Aluminum-copper pcb.
The 3rd One : Iron Based PCB
The iron-based PCB use material for the base is from special steel, silicon steel and ect in stand of FR4 or CEM1 and can dissipate heat away from critical board components and to less crucial areas such as metallic core or the metal heatsink backing.
China PCB manufacturers becomes more and more professional on Iron-Based PCB.
The Iron-based PCB has all the functions as metal materical and the following particular characteristics:
①Vacancy area convenient for further machinery , procuring and fixing of the base ;
②High mechanic strength,good forther machinery suitable for the assembly heaven electronic parts on its surface;
③Silicon-steel is iron magnetic, and can be applied on micro-motors such as on VTR,FDD.
